Carbon films are a kind of thin film coatings which are mainly composed of the chemical element carbon and they can be applied for electrodes and resistors. Recently, we have synthesized a series of aromatic polyazomethines with ether linkage and have found that they can be a good carbon source with high residue of ~70 wt% after carbonization. To continuing our effort to extend the applications of the aromatic polyazomethines, in this study, carbon thin films were fabricated via spin-coating and carbonization. The molecular structural changes from polyazomethine coatings to carbon thin films as a function of temperature were characterized by using Raman, EDS, and FT-IR spectroscopy. The optical properties of the polyazomethine-derived carbon thin films were investigated with aid of UV-visible absorption/luminescence spectroscopy. The electrical properties of the carbon films were also characterized by obtaining current-voltage curves. |
